改进型合并净化槽处理生活污水的影响因素
Factors influencing domestic sewage treatment with modified Merger Johkaso
摘要
Abstract
To improve the Merger Johkaso technology, a micro-electrolysis bed and complex biological fillers were set up in a test, and an anaerobic-anoxic-aerobic (A2/O) bioreactor system was designed to treat domestic wastewater. In order to optimize the performance of the system, chemical oxygen demand (COD), and TN and TP removal rates of the system were investigated, with full consideration of the influences of three major controlling factors: the hydraulic retention time, the organic loading rate, and the sludge reflux ratio. Based on long-term treatment results, the best removal rates of COD, TN, and TP were 95% , 63%, and 87% , respectively, when the hydraulic retention time was at 8 h. When the organic loading rate was 2.7 g·L·1 ·d-1, the average removal rates of COD, TN, and TP were 90% , 74% , and 88% , respectively. When the sludge reflux ratio was 75% , the average removal rates of COD, TN, and TP were 95% , 70% , and 94%, respectively.关键词
